Advances in artificial intelligence (AI), particularly generative AI, hold promise for transforming medical education and physician training in response to increasing health-care demands and shortages in the global health-care workforce. Meanwhile, challenges remain in the effective and equitable integration of AI technology into medical education and physician training worldwide. This Viewpoint explores the opportunities and challenges of such an integration. We study the evolving role of AI in medical education, its potential to enhance high-fidelity clinical training, and its contribution to research training using real-world examples. We also highlight ethical concerns, particularly the unclear boundaries of appropriate use of AI and call for clear guidelines to govern the integration of AI into medical education and physician training. Furthermore, this Viewpoint discusses practical constraints, including human, financial, and resource constraints, in AI integration, and emphasises the need for comprehensive cost evaluations and collaborative funding models to support the sustainable implementation of AI integration. A tight collaborative network between health-care institutions and systems, medical schools and universities, industry partners, and education and health-care regulatory agencies could lead to an AI-transformed medical education and physician training scheme that ultimately supports the adoption and integration of AI into clinical medicine and potentially brings about tangible improvements in global health-care delivery.
人工智能,特别是生成式人工智能的进步有望改变医学教育和医生培训,以应对日益增长的保健需求和全球保健人力短缺。与此同时,在有效和公平地将人工智能技术融入全球医学教育和医生培训方面仍然存在挑战。本观点探讨了这种整合的机遇和挑战。我们研究了人工智能在医学教育中的不断发展的作用,它在提高高保真临床培训方面的潜力,以及它对研究培训的贡献。我们还强调了伦理问题,特别是适当使用人工智能的界限不明确,并呼吁制定明确的指导方针,以管理将人工智能纳入医学教育和医生培训。此外,本观点还讨论了人工智能集成中的实际限制,包括人力、财务和资源限制,并强调需要进行全面的成本评估和协作资助模式,以支持人工智能集成的可持续实施。在卫生保健机构和系统、医学院和大学、行业合作伙伴以及教育和卫生保健监管机构之间建立紧密的协作网络,可能导致人工智能转化的医学教育和医生培训计划,最终支持将人工智能采用和整合到临床医学中,并有可能为全球卫生保健服务带来切实改善。

<div><h3>Background</h3><div>The Global Registry of Acute Coronary Events (GRACE) scoring system guides the management of patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) according to current guidelines.

A machine learning model for 1-year mortality was developed in 400 054 patients from England, Wales, and Northern Ireland. Both the in-hospital mortality model and the new 1-year mortality model were externally validated in patients from Sweden, Switzerland, Germany, Denmark, Spain, the Netherlands, and Czechia. A separate machine learning model to predict the individualised effect of early versus delayed invasive coronary angiography and revascularisation on a composite primary outcome of all-cause death, non-fatal recurrent myocardial infarction, hospital admission for refractory myocardial ischaemia, or hospital admission for heart failure at a median follow-up of 4·3 years was developed and externally validated in participants from geographically different sets of hospitals in the Danish VERDICT trial.</div></div><div><h3>Findings</h3><div>The in-hospital mortality model (area under the receiver operating characteristic curve [AUC] 0·90, 95% CI 0·89–0·91) and the 1-year mortality model (time-dependent AUC 0·84, 95% CI 0·82–0·86) showed excellent discriminative abilities on external validation across all countries. Both models were well calibrated and decision curve analyses suggested favourable clinical utility. Compared with score version 2.0, both models provided improved discrimination and risk reclassification. The individualised treatment effect model effectively identified patients who would benefit from early invasive management on external validation. Patients with high predicted benefit had reduced risk of the composite outcome when randomly assigned to early invasive management (hazard ratio 0·60, 95% CI 0·41–0·88), whereas patients with no-to-moderate predicted benefit did not (1·06, 0·80–1·40; p<sub>interaction</sub>=0·014).

背景:全球急性冠状动脉事件登记(GRACE)评分系统根据现行指南指导非st段抬高急性冠状动脉综合征(NSTE-ACS)患者的管理。然而,性别特异性GRACE 3.0住院死亡率模型,以及预测长期死亡率和早期有创治疗的个性化效果的相应模型,仍然需要广泛的验证。方法:我们使用了2005年1月1日至2024年6月24日来自10个国家的609063例NSTE-ACS患者的数据。对来自英格兰、威尔士和北爱尔兰的40054名患者开发了1年死亡率的机器学习模型。住院死亡率模型和新的1年死亡率模型在瑞典、瑞士、德国、丹麦、西班牙、荷兰和捷克的患者中进行了外部验证。一个单独的机器学习模型,用于预测早期与延迟侵入性冠状动脉造影和血运重建对全因死亡、非致死性复发性心肌梗死、难治性心肌缺血住院、在丹麦的VERDICT试验中,研究人员在来自不同地区医院的参与者中开发并外部验证了中位随访时间为4.3年的心力衰竭住院治疗方法。结果:住院死亡率模型(受试者工作特征曲线下面积[AUC] 0.90, 95% CI 0.89 - 0.91)和1年死亡率模型(时间相关AUC 0.84, 95% CI 0.82 - 0.86)在所有国家的外部验证中都显示出出色的判别能力。两种模型都经过了很好的校准,决策曲线分析显示了良好的临床应用。与评分2.0版本相比,两种模型都提供了更好的识别和风险再分类。个体化治疗效果模型在外部验证中有效识别了早期有创治疗的受益患者。当随机分配到早期有创治疗时,预测获益高的患者的综合结局风险降低(风险比0.60,95% CI 0.41 - 0.88),而预测获益无至中度的患者则没有(1.06,0.80 - 1.40;p相互作用= 0.014)。个体化治疗效果模型表明,受益于早期干预的NSTE-ACS患者群体可能未被当前的治疗策略完全捕获。解释:更新后的GRACE 3.0评分系统为NSTE-ACS患者的个性化风险评估提供了一个经过验证的实用工具。预测早期侵入性治疗对个体心血管的长期益处可以完善未来的试验设计。资助:瑞士心脏基金会、苏黎世大学基金会、Kurt and Senta Herrmann基金会、Theodor and Ida Herzog-Egli基金会、心血管研究基金会-苏黎世心脏之家。

Digital health feedback technologies are expected to help address the projected 630 million individuals with prediabetes worldwide by 2045. This Viewpoint article characterises the historical use of continuous glucose monitoring (CGM) systems in behavioural research with a focus on the prediabetic population. We identified 19 peer-reviewed studies through a pragmatic literature review and reported key methodological features, including study design, sensor wear protocols, data masking strategies, the role of CGM in behavioural interventions, and approaches to generate CGM metrics. Based on our literature review, we propose four directions to advance CGM in behavioural intervention research in prediabetes: refining sampling strategies to focus recruitment on individuals with prediabetes to better understand metrics in this population; improving transparency in CGM feedback delivery protocols; reporting a comprehensive and targeted set of CGM metrics; and articulating principles that account for the effects of CGM use within behavioural interventions. This methodological characterisation of CGM is a starting point to enhance research quality and behavioural intervention effectiveness, particularly when integrating CGM systems aimed at supporting dietary, physical activity, or lifestyle modifications among people with prediabetes.
预计到2045年,数字健康反馈技术将帮助解决全球6.3亿糖尿病前期患者的问题。这篇观点文章描述了连续血糖监测(CGM)系统在行为研究中的历史应用,重点是糖尿病前期人群。我们通过实用的文献综述确定了19项同行评议的研究,并报告了关键的方法学特征,包括研究设计、传感器佩戴方案、数据屏蔽策略、CGM在行为干预中的作用,以及生成CGM指标的方法。基于我们的文献综述,我们提出了在前驱糖尿病行为干预研究中推进CGM的四个方向:改进抽样策略,将招募重点放在前驱糖尿病患者身上,以更好地了解这一人群的指标;提高CGM反馈交付协议的透明度;报告一套全面和有针对性的CGM指标;阐明在行为干预中使用CGM的影响的原则。CGM的方法学特征是提高研究质量和行为干预有效性的起点,特别是在整合旨在支持糖尿病前期患者饮食、身体活动或生活方式改变的CGM系统时。

<div><h3>Background</h3><div>The number of liver transplants from donors after the circulatory determination of death continues to increase, helping to alleviate the existing organ shortage. However, the rate of attempted but subsequently terminated procurements, known as futile procurements, remains high—mainly because many potential donors do not progress to death within a timeframe after extubation that maintains the suitability of the organ for donation. Futile procurements pose considerable financial and workload burdens to the transplant system. We aimed to develop and validate a machine-learning model to better predict progression to death and reduce futile procurements in cases of donation after circulatory death (DCD).</div></div><div><h3>Methods</h3><div>This study included data from 2221 donors from six centres in the USA. Using a retrospective dataset obtained from 1616 donors between December 1, 2022, and June 30, 2023, we developed a prediction model using the Light Gradient Boosting Machine (LightGBM) framework, with neurological, biochemical, respiratory, and circulatory parameters as predictors. The model was validated retrospectively with data from 398 donors (July 1–Aug 31, 2023) and prospectively with data from 207 donors (March 1–Sept 30, 2024). The performance of the model was evaluated through the area under the receiver operating characteristic curve (AUC), accuracy, futile procurement rate, and missed opportunity rate. We also compared the performance of the model with that of two existing risk-prediction tools (the DCD-N score and the Colorado Calculator) and surgeon predictions.</div></div><div><h3>Findings</h3><div>Of the 2221 DCD donors in this study, 1260 progressed to death, 927 of whom died within 30 min after extubation. Cross-validation of the LightGBM model yielded AUCs for predicting donor progression to death of 0·833 (95% CI 0·798–0·868) at 30 min, 0·801 (0·767–0·834) at 45 min, and 0·805 (0·770–0·841) at 60 min after extubation. This performance was maintained in both retrospective (0·834 [0·772–0·891], 0·819 [0·757–0·870], and 0·799 [0·737–0·855]) and prospective (0·831 [0·768–0·885], 0·812 [0·749–0·874], and 0·805 [0·740–0·868]) validation cohorts. Compared with surgeon predictions, the LightGBM model had lower futile procurement rates (0·195 <em>vs</em> 0·078, respectively), higher accuracy in cases of poor intersurgeon agreement (0·08 <em>vs</em> 0·29) at 30 min, and similar missed opportunity rates (0·155 <em>vs</em> 0·167). By contrast, the DCD-N score had AUCs of 0·799 (95% CI 0·730–0·860) at 30 min, 0·760 (0·695–0·824) at 45 min, and 0·739 (0·668–0·801) at 60 min, and the Colorado Calculator had AUCs of 0·694 (0·616–0·768), 0·669 (0·596–0·742), and 0·663 (0·585–0·736) at the same timepoints.</div></div><div><h3>Interpretation</h3><div>We show that, compared with surgeon predictions and existing risk-prediction tools, our machine-learning model can enhance the accuracy of the prediction of progression
背景:供体在循环确定死亡后进行肝脏移植的数量不断增加,有助于缓解现有的器官短缺。然而,尝试采购但随后终止的比率,即所谓的无效采购,仍然很高,主要是因为许多潜在的捐赠者在拔管后维持器官适合捐赠的时间范围内没有进展到死亡。无效的采购给移植系统带来了相当大的财政和工作量负担。我们的目标是开发和验证一个机器学习模型,以更好地预测死亡进程,并减少循环性死亡(DCD)后捐赠的无效采购。方法:本研究包括来自美国六个中心的2221名献血者的数据。利用从2022年12月1日至2023年6月30日期间获得的1616名供体的回顾性数据集,我们使用光梯度增强机(LightGBM)框架开发了一个预测模型,以神经、生化、呼吸和循环参数作为预测因子。该模型通过398名捐赠者(2023年7月1日至8月31日)的回顾性数据和207名捐赠者(2024年3月1日至9月30日)的前瞻性数据进行了验证。通过受者工作特征曲线下面积(AUC)、准确率、无效采购率和错失机会率来评价模型的性能。我们还将该模型的性能与两种现有的风险预测工具(DCD-N评分和Colorado Calculator)和外科医生的预测进行了比较。结果:在本研究的2221例DCD供者中,1260例进展至死亡,其中927例在拔管后30分钟内死亡。交叉验证LightGBM模型得出预测供体进展至死亡的auc,拔管后30分钟为0.833 (95% CI 0.798 - 0.868), 45分钟为0.801(0.767 - 0.834),60分钟为0.805(0.770 - 0.841)。在回顾性(0.834[0.772 - 0.891]、0.819[0.757 - 0.870]和0.799[0.737 - 0.855])和前瞻性(0.831[0.768 - 0.885]、0.812[0.749 - 0.874]和0.805[0.740 - 0.868])验证队列中均保持这种效果。与外科医生预测相比,LightGBM模型具有较低的无效采购率(分别为0.195和0.078),在30分钟内外科医生间一致性差的情况下准确性更高(0.08和0.29),错失机会率相似(0.155和0.167)。相比之下,DCD-N评分在30分钟、45分钟和60分钟的auc分别为0.799 (95% CI 0.730 - 0.860)、0.760(0.695 - 0.824)和0.739(0.668 - 0.801),科罗拉多计算器在同一时间点的auc分别为0.694(0.616 - 0.768)、0.669(0.596 - 0.742)和0.663(0.585 - 0.736)。解释:我们表明,与外科医生的预测和现有的风险预测工具相比,我们的机器学习模型可以提高预测DCD供者死亡进展的准确性,并减少徒劳的采购。这种改进有可能减轻移植界的一些财政和操作负担。需要进一步改进以减少错失的机会并提高此类模型的整体准确性。资金:没有。

We also compared the performance of the model with that of two existing risk-prediction tools (the DCD-N score and the Colorado Calculator) and surgeon predictions.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Findings&lt;/h3&gt;&lt;div&gt;Of the 2221 DCD donors in this study, 1260 progressed to death, 927 of whom died within 30 min after extubation. Cross-validation of the LightGBM model yielded AUCs for predicting donor progression to death of 0·833 (95% CI 0·798–0·868) at 30 min, 0·801 (0·767–0·834) at 45 min, and 0·805 (0·770–0·841) at 60 min after extubation. This performance was maintained in both retrospective (0·834 [0·772–0·891], 0·819 [0·757–0·870], and 0·799 [0·737–0·855]) and prospective (0·831 [0·768–0·885], 0·812 [0·749–0·874], and 0·805 [0·740–0·868]) validation cohorts. Compared with surgeon predictions, the LightGBM model had lower futile procurement rates (0·195 &lt;em&gt;vs&lt;/em&gt; 0·078, respectively), higher accuracy in cases of poor intersurgeon agreement (0·08 &lt;em&gt;vs&lt;/em&gt; 0·29) at 30 min, and similar missed opportunity rates (0·155 &lt;em&gt;vs&lt;/em&gt; 0·167). By contrast, the DCD-N score had AUCs of 0·799 (95% CI 0·730–0·860) at 30 min, 0·760 (0·695–0·824) at 45 min, and 0·739 (0·668–0·801) at 60 min, and the Colorado Calculator had AUCs of 0·694 (0·616–0·768), 0·669 (0·596–0·742), and 0·663 (0·585–0·736) at the same timepoints.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Interpretation&lt;/h3&gt;&lt;div&gt;We show that, compared with surgeon predictions and existing risk-prediction tools, our machine-learning model can enhance the accuracy of the prediction of progression","PeriodicalId":48534,"journal":{"name":"Lancet Digital Health","volume":"7 10","pages":"Article 100918"},"PeriodicalIF":24.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145524521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial intelligence (AI) is set to transform the care of women with cancer. From early detection via digital phenotyping to diagnosis, treatment, and follow-up, innovative AI applications are rapidly emerging across the cancer care continuum. AI-assisted mammographic screening for breast cancer has been clinically translated, and AI-based contouring in radiotherapy is streamlining treatment planning and improving consistency of cancer care. Research areas include radiomic analysis for ovarian tumour characterisation, machine learning for endometrial cancer subtyping, and automated assessment for cervical cancer screening. Challenges such as data scarcity and tumour heterogeneity in gynaecological cancers hinder the development of robust AI models, a problem further compounded by the limited availability of large, prospective validation cohorts. Emerging generative AI and multimodal AI systems hold promise to address these limitations by leveraging large-scale, diverse training datasets. Building trust in AI systems will require rigorous prospective real-life validation, regulatory oversights, and well-defined legal frameworks. A key opportunity exists to develop inclusive, clinically meaningful AI devices across all women’s cancers, driven by rapid advances in AI in health care and strengthened by national and international initiatives promoting health-care innovation. Through multidisciplinary collaboration, AI has the potential to move beyond research and help in early diagnoses and provide personalised treatment strategies. In this Series paper, we review AI developments in breast and gynaecological cancers, including applications in clinical adoption and those actively being developed to address unmet needs in early detection, characterisation, treatment, and prognostication.
人工智能(AI)将改变女性癌症患者的护理方式。从通过数字表型进行早期检测到诊断、治疗和随访,创新的人工智能应用正在整个癌症治疗过程中迅速涌现。人工智能辅助乳腺癌乳房x线摄影筛查已在临床上转化,基于人工智能的放射治疗轮廓正在简化治疗计划并提高癌症护理的一致性。研究领域包括卵巢肿瘤特征的放射学分析,子宫内膜癌亚型的机器学习,以及宫颈癌筛查的自动评估。数据稀缺和妇科癌症的肿瘤异质性等挑战阻碍了强大的人工智能模型的发展,而大型前瞻性验证队列的有限可用性进一步加剧了这一问题。新兴的生成式人工智能和多模态人工智能系统有望通过利用大规模、多样化的训练数据集来解决这些限制。建立对人工智能系统的信任需要严格的前瞻性现实验证、监管监督和明确的法律框架。在人工智能在卫生保健领域的快速发展推动下,并在促进卫生保健创新的国家和国际举措的加强下,存在着开发适用于所有妇女癌症的具有包容性和临床意义的人工智能设备的关键机遇。通过多学科合作,人工智能有可能超越研究,帮助早期诊断,并提供个性化的治疗策略。在本系列论文中,我们回顾了人工智能在乳腺癌和妇科癌症中的发展,包括在临床应用中的应用,以及那些正在积极开发的用于解决早期检测、表征、治疗和预后方面未满足需求的应用。

Background

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality, yet early detection remains challenging. This study assessed whether deep learning applied to routine outpatient chest radiographs (CXRs) can identify individuals at high risk of incident COPD.

Methods

Using cancer screening trial data, we previously developed a convolutional neural network (CXR-Lung-Risk) to predict lung-related mortality from a CXR image. In this retrospective model validation study, we externally validated whether CXR-Lung-Risk was associated with incident COPD from routine CXRs. We identified outpatients without lung cancer, COPD, or emphysema who had a CXR taken from Jan 1, 2013, to Dec 31, 2014, at Massachusetts General or Brigham and Women’s Hospitals in Boston, MA, USA. The primary outcome was 6-year incident COPD. Discrimination was assessed using area under the receiver operating characteristic curve (AUC) compared with the TargetCOPD clinical risk score. All analyses were stratified by smoking status. A secondary analysis was conducted in the Project Baseline Health Study (PBHS) to test associations between CXR-Lung-Risk with pulmonary function and plasma protein abundance. The PBHS study is registered with ClinicalTrials.gov, NCT03154346.

Findings

The primary analysis consisted of data from 12 550 ever-smokers (mean age 62·4 years [SD 6·8], 6135 [48·9%] male, 6415 [51·1%] female) and 15 298 never-smokers (mean age 63·0 years [8·1], 6550 [42·8%] male, 8748 [57·2%] female). 1562 (12·4%) of 12 550 ever-smokers and 580 (3·8%) of 15 298 never-smokers developed COPD within 6 years. CXR-Lung-Risk had additive predictive value beyond the TargetCOPD score for 6-year incident COPD in both ever-smokers (CXR-Lung-Risk + TargetCOPD AUC 0·73 [95% CI 0·72–0·74] vs TargetCOPD alone AUC 0·66 [0·65–0·68], p<0·0001) and never-smokers (CXR-Lung-Risk + TargetCOPD AUC 0·70 [0·67–0·72] vs TargetCOPD alone AUC 0·60 [0·57–0·62], p<0·0001). In secondary analyses of 2097 individuals in the PBHS, CXR-Lung-Risk was associated with worse pulmonary function and with abundance of SCGB3A2 (secretoglobin family 3A member 2) and LYZ (lysozyme), proteins involved in pulmonary physiology.

Interpretation

In this external validation, a deep-learning model applied to routine CXR images identified individuals at high risk of incident COPD, beyond known risk factors. Patients at high risk might benefit from diagnostic spirometry and subsequent preventive care.

背景:慢性阻塞性肺疾病(COPD)是导致死亡的主要原因之一,但早期发现仍然具有挑战性。本研究评估了应用于常规门诊胸片(cxr)的深度学习是否可以识别COPD高危人群。方法利用癌症筛查试验数据,我们先前开发了一个卷积神经网络(CXR- lung- risk),从CXR图像预测肺部相关死亡率。在这项回顾性模型验证研究中,我们从外部验证了CXR-Lung-Risk是否与常规cxr引起的COPD事件相关。我们确定了2013年1月1日至2014年12月31日在美国马萨诸塞州波士顿的马萨诸塞州总医院或布里格姆妇女医院进行CXR的无肺癌、COPD或肺气肿的门诊患者。主要终点为6年COPD发生率。采用受试者工作特征曲线下面积(AUC)与TargetCOPD临床风险评分进行比较,评估其辨别性。所有分析均按吸烟状况分层。在项目基线健康研究(PBHS)中进行了二次分析,以测试cxr -肺风险与肺功能和血浆蛋白丰度之间的关系。PBHS研究已在ClinicalTrials.gov注册,注册号为NCT03154346。结果主要分析了12 550例吸烟者(平均年龄62.4岁[SD 6.8],男性6135例[48.9%],女性6415例[51.1%])和15 298例从不吸烟者(平均年龄60.3岁[8.1],男性6550例[42.8%],女性8748例[57.2%])的资料。12550名曾经吸烟者中有1562人(12.4%)和15298名从不吸烟者中有580人(3.8%)在6年内发展为慢性阻塞性肺病。对于吸烟者(CXR-Lung-Risk + TargetCOPD AUC 0.73 [95% CI 0.72 - 0.74] vs单独TargetCOPD AUC 0.66 [0.65 - 0.68], p< 0.0001)和从不吸烟者(CXR-Lung-Risk + TargetCOPD AUC 0.70 [0.67 - 0.72] vs单独TargetCOPD AUC 0.60 [0.57 - 0.62], p< 0.0001)的6年COPD事件,CXR-Lung-Risk在TargetCOPD评分之外具有附加预测价值。在对2097名PBHS患者的二次分析中,CXR-Lung-Risk与肺功能恶化以及SCGB3A2(分泌珠蛋白家族3A成员2)和LYZ(溶菌酶)的丰度有关,这些蛋白与肺生理有关。在这个外部验证中,应用于常规CXR图像的深度学习模型识别了超出已知危险因素的COPD高风险个体。高风险患者可能受益于诊断性肺活量测定和随后的预防性护理。FundingVerily Life Sciences, San Francisco, California。

Computer-aided detection (CAD) systems for automated reading of chest x-rays (CXRs) have been developed and approved for tuberculosis triage in adults but not in children. However, CXR is frequently the only adjunctive tool for clinical assessment in the evaluation of paediatric tuberculosis in primary care settings, and children would benefit from CAD models that can detect their unique clinical and radiographic features. To advance CAD for childhood tuberculosis, large, diverse paediatric CXR datasets linked to standardised tuberculosis classifications are required. These datasets would be used to train and validate paediatric-specific models for tuberculosis screening, diagnosis, and severity stratification. Previous studies on CAD algorithms for reading paediatric CXRs have highlighted promising approaches, including the use of transfer learning with existing deep learning models. Including data from children in CAD models is essential to improve equity and reduce the global burden of tuberculosis disease.
用于自动读取胸部x光片(cxr)的计算机辅助检测(CAD)系统已被开发并批准用于成人结核病分诊,但未用于儿童。然而,在初级保健机构中,CXR通常是临床评估儿科结核病的唯一辅助工具,儿童将受益于CAD模型,该模型可以检测其独特的临床和放射学特征。为了推进儿童结核病的CAD,需要与标准化结核病分类相关的大型、多样化的儿科CXR数据集。这些数据集将用于训练和验证用于结核病筛查、诊断和严重程度分层的儿科特异性模型。先前关于阅读儿科cxr的CAD算法的研究强调了有前途的方法,包括将迁移学习与现有的深度学习模型结合使用。将儿童数据纳入CAD模型对于提高公平性和减少结核病的全球负担至关重要。
